I created an issue and a PR to include this:

I think it would be worth including - after some consideration perhaps.
There is already an old-style sysv init script in the Fuseki distribution after 
all.

However, I would like some discussion first about what the proper way is to
install Fuseki as a system level service on a typical Linux machine.
As you can see from the tutorial I linked to from my previous message, it's
currently a bit cumbersome to make it comply to the FHS. Naturally the chosen
directory layout also affects the systemd unit file.

Maybe the best way to proceed is to put a script in now so it gets 
picked up in the next release and not worry too much about the details 
but instead mark it "experimental" or "template to start from".


We can discuss details we know about but often its the things other 
users have in their systems that generate concerns we can not know.

CentOS 7/systemd startup script for fuseki

[Neubert, Joachim]

Hi everybody,

Has anybody a proper systemd startup script for fuseki in place?

So far I use an entry for the "fuseki" init.d script in /etc/rc.local, which 
works after making the latter executable. But perhaps the problem has been 
solved in a better way.

Cheers, Joachim
